Guake Wayland/Xwayland issues with application blur (Blur My Shell Extension)

[Kostrol]

Be sure to check the existing issues (both open and closed!), and make sure you are running the latest version of Guake.

For how to run the latest Guake in your computer, please refer to Install from source.

Describe the bug

Guake does not show blur when opened until another application is focused in Wayland/Xwayland

Expected behavior

Guake should open/toggle in blurred state with applications blur enabled in "Blur My Shell" extension

Actual behavior

Guake seems to have an issue with remembering blurred state, this is only tied to Wayland.
Opens without blur effect and does not kick in until you focus an application, resets again after being re-toggled to background

To Reproduce

Using guake-toggle with Wayland, combined with blur my shell extension and application blur on, guake opens without blur, toggle again to minimize gake to background and then toggle to foreground, guake is now unblurred again.

Guake has its own transparency setting that may be interfering with external effects. What happens if you turn the transparency slider built into Guake all the way down?

[Kostrol]

I've always had it set to the lowest point due to the issues with transparency it causes, the effect I'm getting happens regardless if it's on or off.

[Davidy22]

Code looks like it does still do the transparency setting even when it's at nothing, I still suspect that should be the source of the issue given that I can't think of any other part of Guake that would collide with external effects

[Kostrol]

I see, If that is the case would it be a way to disable it completely to test?

Here is how the transparency slider works for me when it's turned up about half way with Blur My Shell extension disabled completely, it does not seem to work like expected on programs like btop and only lets transparency through the parts of the window where only the terminal pane is showing, and where you can see I have right clicked in Tmux where the menu window is showing.

EDIT: Now that I think about it that does make sense with how Guake would apply it only to the plain terminal itself and no programs, and they would need their own implementation, so I guess this is the intended function.

[Davidy22]

The default keyboard shortcut for fully toggling transparency in Guake is CTRL+ALT+T. You can change the shortcut if you have that overridden in keybinding settings, it's under appearance. Doesn't have a button because usually it's rendered moot by what you would expect to be the functionally equivalent 0 transparency setting.

[Kostrol]

Thank you, unfortunately toggling off transparency in Guake did not fix the bug like you mentioned and it still disables blur and transparency between calling/toggling Guake to spawn, there is some strange focus issue that I don't really understand, I've submitted an issue to the extension's maintainer as well way back but haven't seen any update as of yet.
